Global Specialties Mosquito Repellent Kit

This circuit generates a frequency 10-30 kHz that creates a sonic zone disturbing to mosquitoes.

A piezo board creates the frequency equal to the frequency generated by the mosquito during flight causing the mosquito to believe he/she is flying into a trap.

Technical Specifications:

• Power Source: 3 VDC
• Power consumption: 20 mA max.
• PCB dimensions: 1.60 x 1.39 inches

Operating Principles:

• Transistor 1 and 2 control low frequency 10 kHz, while transistors 3 and 4 control high frequency 30 kHz.
• This circuit is designed to alternate the frequency.
